changes/bug27658

+  o Minor bugfixes (testing):
+    - If a unit test running in a subprocess exits abnormally or with a
+      nonzero status code, treat the test as having failed, even if
+      the test reported success. Without this fix, memory leaks don't cause
+      cause the tests to fail, even with LeakSanitizer. Fixes bug 27658;
+      bugfix on 0.2.2.4-alpha.
